SPRING' UPHOLSTERY DEVICE.

f Sinecicati-onv of Letters Patent. Patented e Applicationk filed vApril 11, 1910. Serial No. 554,845. i

To' all 'whom it'ra'y concern: '4 l '-Be it known that we, ,MAX Fina and UL RICH FEiG, subjects of the King of Saxony,

residing at BadA Elster, Vogtland, in Grerman-y, have invented a certain newand use- I ful Improvement in Spring Upholstery De.

Figure 1 is a plan View of the mattress,

and Fig. 2 a side view thereof. Fig. 3 is a section of part ofthe mattress on the line IIIIII of Fig. l, and on an enlarged scale, showing one of the box-springs with its centering and regulating device. Fig. 4 is a View similar to Fig. 3, but showing another forrn of the centering device. Fig. 5 is a perspective View showing part of one -of the springs, with its attachment to the upper network of the mattress. Fig. 6 shows the centering and regulating device of Fig. 3, on a larger scale. Fig. 7 shows the centering and regulating device of Fig. 4 in section, and on a larger scale. Fig. 8 is a bottom plan view of Fig. 7

The mattress shown in Figs. 11 and 2 com prises a kind 'of net formed of rings 1 connecting hooked rods or links 2, this net be` ing supported by. box-springs 3, and con- I nected by coiled springs 4 to the head and foot rails 21 of a frame. One of the springs 3 is shown on a larger scale in Fig. 3, which also illustrates y:the means whereby the net vis attached to the side rails of the frame. The device used for this purpose comprises a togglelever 7, 8 pivoted at its lower end to the rail 6, and engaged at its upper end with a wire9 which is stretched along the side oil the mattress, the ends of the wire 9 being connected to the head and foot rails by springs 41. lCords 11 attached to the lateral edges of the net pass over the wire 9 and are attached to the rail 6, and a sp1-ing 10 with one end connectedl to said rail is pulled rails.

toggle-lever is formed of two parallel strips of metal, bent at their. ends to make eyes for engagement with the wiref) and. memb'en respectively. The springs 3y are supported Nov. 14s,' 1911. Y

connected at its other eriddto the knuckle oft the A.toggle-lever. 7, 8. The member 8 of the by cords 12 which form a network attached i to the sides and ends of theframe, the connection of the springs to this network being made by means Iofsupports 13,'one of which. l 1s shown in Fig. 6.-' This support 13 con-` i sists of-a hollow truncated cone with "any lindric'alextension atits base. A helical ridge or thread 140 is formed'upon the cy`v` lindrical part .of this support, fo'rvengaging'@ 'l it with the helicalspring 3 as shown. double hook lwith screwfthreaded shank is suspended in the cone, to .which itis fixed 'by means of a wing-nut 15 screwed down upon the flat .top of the support. The latter is placednt the point of .intersection of two' cords 12, land one of the latter is engaged with both the hook-members, the other cord 12 passing between these members overI the engaged cord 12. The tension of the cords 12 can be regulated by screwing'the nut 15,

so-that the hook is either pulled upward ori lowered in the part 13. While the cords 12 are slack, but engaged with the hook, the support- 13 can be easily adjusted so that it is exactly coaxial with the uppermost convolution of the spring 3. This adjustability is very important in regard to the efficiency and life of the springs 3. The latter are of the conical type, with convolutions increasing in diameter toward the top. The l connection of the springs 3 to the rods 2 is made in known manner by means of strong henipen cords 16; by this means friction of metal on metal is avoided, and the action of the springs rendered noiseless. The cords 12 are fastened by screws 17 to the side rails 6 and transverse railse18 of the frame; the

'rails 18 are dove-tailed to the rails 6, and

fixed by screws 19.A The axes of the screws 19 are outside the median lines 'of the rails 18, which prevents wabhling of the inwardly cone, without cylindrical extension, used in conjunction with a box-spring 31 whichis flared both at top and bottom. The support The side rails f5 are fixed to' l 131-is connected to thelspring 31 by radially .also engage the said cords and then curve back over the spring 31. The shanks of the hooks 23 are tted into holes in the part 131,

so that the hooks are normally slightly ,downwardl inclined, and are bent upward to engage t e spring 31.- l

What we claim as our in'vention and desire to secure by Letters Patent of the United States is l 1. In an upholstery cushioning device, the combination of a webbing, a plurality of box 'springs supported on said webbing, domed devices engaging said springs and having bearing on the webbing and means within- 'said domed devices for applying tension to the webbing;

2. In an upholstery cushioning device the combination of a .webbiiig,` aV plurality of box springs supported on said webbinggperipheral means engaging Vthe lower ends of said springs and a hooked member adapted to be drawn upward within the periphery of said means for tensioning thel webbing.

3. In 'an upholstery lcushioning device the combination of a webbing composedof 4crossed cords, box springs located at the in# tersections of said cords domed devices peripherally engaging the springs, hooks adapted to 'engage the webbing at the points of intersecting and means for drawing said hooks into said domed devices to tension said webbing. 4

In witness whereof we have signed this specification in the presence of vtwmwitnesses. f
